What are the differences between async/await and callbacks in Node.js?

What are the differences between async/await and callbacks in Node.js?

Async/await is syntactic sugar over promises, making asynchronous code easier to read and write compared to callbacks.

Can you give me an example of how to use async/await?

Sure! Here's a simple example:

async function fetchData() {
    const response = await fetch('https://api.example.com/data');
    const data = await response.json();
    return data;
}

What are the advantages of using async/await over callbacks?

Async/await leads to cleaner code, avoids callback hell, and makes error handling easier with try/catch blocks.

Are there any downsides to using async/await?

One downside is that async/await can lead to performance issues if overused in tight loops, as it introduces more overhead.
